Generate PrefixMap constants from Mixin attributes
- Add PrefixMapGenerator to produce COMPOSABLE/COMPOSABLE_WITH_ARGUMENT
  constants from #[Mixin] attributes, replacing hand-written arrays
- Move Prefix transformer to reference generated PrefixMap constants
- Extract NamespaceScanner from MixinGenerator for shared directory scanning
- Introduce FluentBuilder subnamespace for builder-chain generators
  (MixinGenerator, PrefixMapGenerator, MethodBuilder, Mixin attribute)
- Add CodeGenerator interface and Config class as shared CodeGen contracts
